Cufflinks Candlestick Chart Error in Google Colab

Question

I am a newbie in Google Colab. I just wanna create a candlestick chart but I saw errors everytime I have tried. The code is as follows.

import pandas as pd
import yfinance as yf
df_twtr = yf.download('TWTR',
start='2018-01-01', end='2018-12-31', progress=False, auto_adjust=True)
import cufflinks as cf
from plotly.offline import iplot, init_notebook_mode 
init_notebook_mode()
qf = cf.QuantFig(df_twtr, title="Twitter's Stock Price", legend='top', name='TWTR')
qf.add_volume()
qf.add_sma(periods=20, column='Close', color='red')
qf.add_ema(periods=20, color='green')
qf.iplot()

I can create the plot in JupyterLab , it works well. But gives error in Colab. How can I solve that problem? Thank you.
